It's a bit disappointing when you see reviews based on fitment for a UNIVERSAL part. Right there that nullifies one's ability to complain about how it fits. It'd be great if we could just review the part for what it is. As far as this pump goes, i've been very, very happy with it. I've been able to experience several, several drop in fuel pumps over the years on my own cars and other cars i've worked on, and this has so far been the most reliable and durable, especially when you add ethanol into the equation. As an added bonus, it's quiet and really reasonably priced. Tons of bang for your buck here. The best in its class IMO.

Don't make the same mistake I did, get the 310 lph pump as this will not fit our fuel pump housings. 3 stars as I did not get to test it

Aem 320 e85 fuel pump EVO X
Robsdc269810 4 years ago
U love the pump. I made good numbers with it. But fitment is poor on EVO X... You will have to buy the kit or just drop it the fuel pump assembly and zip tie it as I did.. Made 400tq 380hp with minor bots on & E85..

Quality of pump is great.. Reason for the 1 star is poor fitment on the 2004 STI, ample modifications necessary to the fuel pump housing in order for fitment. Will not bolt up and either frame of pump has to be cut or the metal line that the pump connects to has to be modified extremely.

  • Q: Stock WRX injectors  officeinthesky8828317 4 years ago


    Will it be ok to run this pump with my stock 07 WRX injectors?

    • A: This pump can be used with stock injectors.

  • Q: fitment  jonnyruizh1144770 4 years ago


    will this pump fit '12 sti with the universal kit? will e85 diminish the life f the pump?

    • A: Modification to the fuel pump housing will be necessary for a 2012 STI because this pump is larger than stock and you may need a custom size O ring for the connection from the pump to the housing. This pump is made to be E85 compatible and it should not shorten the life of the pump.

  • Q: injector capacity  tempemail55c52177caae52c4048b7f4d 4 years ago


    will this fuel pump work with 1300cc injectors on e85? also with this fuel pump fit an 03 wrx?

    • A: This pump will flow enough as it is made for e85. As this is a universal fit we can't confirm it 100%

  • Q: injector capacity  TuruSTI 4 years ago


    could this pump work with 1000cc injectors or i need a higher volume pump like walbro 400

    • A: Should not be an issue with 1000cc injectors. But you will need to compare the pressure vs flow of this pump, to what you plan on running from your injectors to make sure that it is a correct match.

  • Q: Evo X fitment  Doww Jonez 4 years ago


    On AEM's fitment guide (link below) it shows a specific part number 50-1210 for the Evo X. I've not seen this available for sale anywhere including RallySportDirect. Any word on how it differs and when it will be available?

    • A: The Evo X specific fuel pump is not available as of 3-6-14, but will be released soon. The Evo X specific pump is physically smaller so it will fit in the stock fuel pump housing.
